N5FY’S Elecraft KX1 Minimal CW Kit
by Joshua (N5FY)
I started operating CW this past August and am having a blast! One great thing, or maybe its a bit of a problem for the budget, is that when you can work CW, there is a whole new world of HF radios to collect…I mean operate!
Not to mention the ability to pack out a small portable kit that can be thrown in a bag at the last minute when headed out the door. I have a few such kits but lacked a throw line for each. So, I picked up some more Arborist Throw Line from Atwood Rope Manufacture so I could finish out the first kit.
I just snagged a used, inoperable, KXPD1 paddle to complete my KX1 radio. I had to rebuild the jack on the key but did so in quick order and decided to make it out to my local park for a POTA activation. My plan was to finish up the kit with the throw line and then test out the new complete kit. Suffice to say, all went well!

The KX1, now out of production, has been a pleasure to operate CW with. This unit has the internal ATU option, 6xAA battery pack, and I updated the internals to add 80 and 30m. So this rig will run 20/30/40/80m.
There are 2 message memories, built in keyer, and even includes RF, AF, and bandwidth knobs for quick adjustment while operating. I’m no experienced CW operator, but this rig is hard to beat in my opinion. Then again, my KH1 hasn’t show up yet!

The antenna of choice here is my Tufteln 2 Wire No Transformer with a 41ft radiator and 17ft counterpoise. The internal ATU makes working 20, 30, and 40m simple and with no coax needed. I would use a much longer wire if I needed to work 80m. This antenna packs away very nice and not needing the Coax is a space saver. I have one version or another of my QRP antennas in each of my radio kits!

Packing a kit with no room to spare is almost like playing Tetris. I have a good bit of gear from Go Ruck, its all fantastic. For this kit, the 3L would leave a bit more space for some additional gear. If you are looking for some pockets as well, I like the GR2 Field Pocket. For this KX1 though, with the cover installed, I happed to forgo the bit of extra protection for the lightweight small size.

As I often do, I hunted yet another CW POTA activator during my lunch break while working from home.
I have been learning CW for most of the year. Early on, I realized that with a bit of practice sending, and after listening to recordings of POTA activations, like those from Thomas, I could reliably send the proper exchange needed to hunt a POTA activator.
If you can give your call sign, signal report, and state abbreviation, you can make the contact. I started early on with just the basics and then added some of the common “extras” like GM for good morning, TU for Thank You and then 73. Not only is this great practice for getting on the air sending CW, it’s also very rewarding while learning CW. The exchange is short, standard, and easy to follow with a bit of practice.
CW Practice with the Morserino32 and a Cup of Coffee
Once I finished my upgrade to Extra I focused all my spare time, not much though truth be told, on practicing CW.
At some point this summer I set the goal to Activate POTA/SOTA during the W4G SOTA campout this fall. This really wasn’t an aggressive goal, one I figured was attainable but also one that I could hold myself accountable to even knowing I had a very busy summer ahead of me.

During one of the LICW Club classes I heard again that their goal is to get Hams on the air to make a QSO. I thought to myself, yes, that is great, and I want to do more, but I know I have made many QSOs in CW on the air, albeit very short and simple ones. So, I was curious how many.
I jumped on the POTA site and looked up my statistics. I was surprised at how may hundred I had, and yet at the same time, I was a bit disappointed. It’s not that I wanted to have made more CW contacts, it’s that I realized that they were ALL from hunting and not a single one was from calling CQ.
So, I changed my goal.
I know that Hams, especially CW operators, are a great bunch of people and they want to see new CW operators succeed, so there is lots of patience when you call CQ. So, I decided to move up my timeline. This was on a Thursday, and Saturday was a likely candidate for a POTA outing, why not–?
Saturday was my birthday, and I knew I could get away with some personal free time in the morning where I could dive in and call CQ POTA DE N5FY. The next day, Friday, I firmed it up, I would head out in the morning, bring the new to me KX2 and see what happens.
Surprisingly, I was much less nervous than I expected, I had told myself that it wouldn’t help anyways to be nervous so just do it and see what happens. I made it to my local park, to the picnic table I frequent, then setup a No Transformer 2-Wire antenna with the KX2. One press of the ATU button and I had a 1:1 match on 40m band.
Of course, I have great timing. I could not believe the stations on the air on 40m. I never did look but there must have been a contest. I moved up and down about 20kHz and there were stations everywhere! I called “QRL?” on 2 different frequencies and had a reply before I landed on open frequency where I could call CQ.
N5FY First CW Activation KX2 Setup
I had not scheduled the activation; I knew I had a bit of cell phone coverage at this park, so I set the CQ POTA message to calling while I posted a spot.
After two calls, I had my first call back. It was time!
I could have freaked out here, but I was too focused on decoding to even be nervous! Of course, I had to send a partial call and a “?” once or twice to get the full call right. Of course, I made some keying errors. But the caller had patience and worked me and we made the QSO. Now I was really excited!
I called CQ and someone sent me back dits and dahs, and I decoded what they were sending! Boy, this was fun! I continued to call CQ POTA, and tried my best to decode the replies, several pileups, and lots of “?” sent by me. But I was making contacts and having a blast!
After a couple of silent CQ calls later, I switched to 20m. And, again, started to get replies back as well as a couple small pileups. In the end, there were a couple call signs that I could not look up, l had a letter or two wrong, but with almost 20 in the log I knew I had an activation and boy was I happy!

Looking back on the activation, and after talking to another Ham, it occurred to me why I wasn’t as nervous as I thought I might be.
You see, when you are the Activator, when you call CQ, the ball is in your court, you invite people to call back and they are there for you. I almost get more nervous hunting as I don’t want to slow down an activator or run over another caller. But when you are the one calling CQ, it’s your game!
Of course there were several hiccups along the way. For one, it got HOT sitting in the sun. I ended up deploying my hiking chair on the table as a sunshade and pulled a portable fan out of the car. Even the action camera overheated while recording the activation. I couldn’t get the KXPD2 paddle to key the KX2 on 20m when I first got setup. And of course, I had lots of sending errors (although fewer than I expected to have) and sent a A LOT of “?” asking for a repeat.
That said, I am very glad to have jumped in and will continue to activate CW going forward as I continue to build my CW skills. For me, confidence in the ability to Activate on CW is great motivation for practicing, which again, is my biggest learning. If I want to be a good operator, I need to put in the effort, and going out to play radio is one extremely fun way to practice!
I often find myself playing radio in the evening when I travel out of state for work. I especially enjoy adding another state to my list of activations. So, a trip to the Sioux City area was great, as I could activate in South Dakota and Nebraska, both new states to add to my POTA activations.
Of course, you are wondering how one accidentally completes a 3 state POTA rove, so I’ll get into the details in a bit. Believe me though, it wasn’t because I had a fool-proof plan. I do believe that failing to plan is planning to fail. But in this case, a bit of luck and agility on my part, with the bands cooperating, and with the POTA hunter support, I did indeed complete 3 POTA activations, in 3 states, in under 2 hours!
Go Ruck Bullet fits inside the G2 ready for Travel
To be honest, I rarely put much effort into planning an activation while traveling as I simply may not have any time get out to a park, and of course, playing radio is not the purpose of my trip. I often find myself spending just a couple minutes looking at POTA locations before a trip and even may look last minute after I land, before I get off the plane, looking for a good POTA location. Maybe I like the urgent planning excitement, or maybe I don’t want the disappointment of not having the chance to go activate after spending time planning the outing? Again, I do recommend a bit of planning, so don’t exactly follow my example here.
As a result of my minimal planning I typically find myself with a very impromptu, “wing it” style activation. This trip was certainly no exception. I only had one evening to check off both South Dakota and Nebraska. There were parks which seemed readily accessible, but I hadn’t really verified activation numbers or best location on the park property to setup. I did save a few parks in the 3-State area, including Iowa.
I already had an Iowa activation, so I wasn’t as worried about hitting the IA park.
Once my evening freed up, the first day I was in the area, it was already a late in the evening, so I was in a bit of a rush as I headed to the first park. I figured I would hit South Dakota first then drop down to Nebraska and spend a bit more time calling CQ there according to how much daylight I had left.
POTA Park in 3 States surrounding Sioux City
I arrived in the area of the first park–a state park land. As I approached the boundary, I found a horse trail parking lot with some nice-looking trees for a throw line and wire antenna. As I was in a hurry, not needing a hike, I knew this would work well. I’m not one to play radio from the car, but in this case, it would cut down a bit on the time needed so I could get to the second park.
I threw a line and pulled up my antenna. Within 10 minutes of parking, I had my station setup and scanned 20m to see what shape the band was in. I typically put up a 20m EFHW and hope for the best, and this usually doesn’t disappoint. I then setup my log and found a surprise. Continue reading An Accidental Three-State POTA Rove!→
QRP POTA Activation During the CQ World Wide Contest
by Joshua (KO4AWH)
I had an opportunity to activate Fort Yargo State Park (K-2177) during the CQ WW DX contest.
Fort Yargo is my local park, about 30 minutes away. The park features a great playground for the kids to play on and many tall trees which are perfect for deploying a wire antenna. There really is not much more I could ask for in a POTA location. Even the noise floor is very low, about S0, so I typically turn on the pre-amp which brings it up to S2-S3 on my Discovery TX-500.
This was very much a last minute plan. I knew the contest was going on which may present some difficulty activating QRP. I knew I would not be calling CQ on 20m where I normally activate and hunting stations could be difficult but likely doable.
There was a bit of rain at the house in the morning, then a promise of drizzle the rest of the day. Not too sure what I would find at the park, but hopefully the rain would hold off and I could get the activation in using the TX-500 without too much worry about it getting wet. I threw in a picnic blanket with a water barrier that promised a bit of protection from the rain if needed it.
I have a go-box setup with my TX-500 and IC-705, as well as several antennas, an ATU, and all cabling and power needed to run FT8 either on my Raspberry PI4 with the TX-500, or on my iPad through the IC-705.
I was taking my wife’s vehicle as she had the car seats needed for the 3 kiddos that were coming along. So, I had to be sure I had everything I needed. There are quite a few additional radio items I keep in the back of my car that I would not have available. But everything should be in the go-box, right?

After a bit of mist and some rain on the drive over, I planned to setup the TX-500 knowing it would get a bit wet. I tossed the throw line in the tree and pulled up my Tufteln EFHW QRP cut for 20m. In retrospect I probably should have pulled up the EFRW for a bit more band agility.
I tuned around for a few minutes.
Yup, there was not a single free place across 20 meters where I could start calling CQ in the clear. In fact, the stations I listened to for more than a few seconds had someone else start calling right on top of them. 20 meters was indeed crazy.
Back in May I had to travel last minute for work to North Dakota. I typically bring radio gear in the event that I have some time to do a Parks On the Air activation. This trip presented the opportunity to activate a park in Minnesota as well as one in South Dakota. I didn’t have much time to plan these activations, but I knew I had an early enough arrival in the afternoon that I could likely activate a park in MN and then in SD. So, I picked out a park in MN close to my destination. I could go activate in MN then get over to a park in SD and activate there.
I found a nice looking State Park in MN. The idea was to activate as quickly as I could and then get back to a park in ND with enough time to activate before it got too late. K-2482 Fort Snelling State Park had 110 successful activations. That is always promising when planning out an activation. I got my rental car and headed to the park.
I also had recently purchased a HFJ-350m which is a base-loaded coil with an extendable whip. I found a tripod base I could print online and then designed an adapter so I could install a SO-239 and RG316 lead with a BNC connector. I had just tested this setup in the back yard and knew it worked, although I certainly knew it was a compromised antenna.

I typically bring my Raspberry PI4 loaded with Build-A-Pi and then run digital modes from my phone or Tablet. My plan was to activate this park with the compromised antenna running 5W on FT8 at the first park and then go to my second park and run a full half wave wire in a tree on SSB at 10W.
Not much to say about the activation in MN. The state park was nice but where I set up presented quite a bit of RF noise. Not so much of a problem since I was running digital. After a bit of adjustment on the whip I was tuned for 20m and started hunting a few FT8 stations. I did make a few QSOs while hunting but I then started calling CQ and had a bit more luck. I think because my signal was quite weak, calling CQ was a bit more efficient as only those who could hear me were calling back. While hunting, if those calling CQ were running a bit more power, I was unlikely to get in while running lower power and on a compromised antenna. I got the activation completed with 12 QSOs and packed it up and headed to the next park.
